Input and Output Parameter Types

When you looked at the source code for the lgrep program in A Simple Example, you probably noticed the important role of the generic parameter type lpar_t. This type provides a clean, extensible interface for DevKit command functions. A value of type lpar_t is called an lpar, and is pronounced ell-par. Most DevKit command functions take lpars as arguments. An lpar might be a list of other lpars, so you can pass arbitrarily many values as each argument.

This section describes how to create, build, and destroy lpars. Read this section to know everything about passing input parameters to DevKit commands and processing their output.
